Elon Musk explains the delay for Tesla’s autonomous coast-to-coast trip
Elon Musk has finally explained why the company ultimately delayed its 2017 plan for a coast-to-coast autonomous drive, and why he stands firm on Tesla’s three-pronged Autopilot approach for full self-driving over LiDAR technology.
During the Q&A portion of Tesla’s Q4 earnings call, Romit Jitendra Shah of Nomura Instinet asked Musk for any updates on the company’s plans for a fully autonomous coast-to-coast drive. Responding to the inquiry, the Musk explained that Tesla is focused on developing a full self-driving suite that would work on all roads under any conditions — something that would have been compromised had Tesla forced the feat last year.
“We could have done the coast-to-coast drive, but it would have required too much specialized code to effectively game it or make it somewhat brittle and that it would work for one particular route, but not the general solution. So I think we would be able to repeat it, but if it’s just not any other route, which is not really a true solution,” Musk said.
When asked about the timeline for the coast-to-coast autonomous drive, the Tesla CEO stated that it might happen in three months, or “six months at the outside.” Musk further stated that the feature would be available for Model S, X, and 3 customers who purchased the Full Self-Driving (FSD) upgrade for their vehicles. The CEO did not confirm, however, if the feature would be rolled out to customers immediately after the coast-to-coast drive is accomplished, or if customers would have to wait before being able to access the feature.
Perhaps the most interesting part of Musk’s statements about FSD, however, came from David Tamberrino of Goldman Sachs. During the Q&A session, Tamberrino asked Musk about his comments on LiDAR technology, a particularly prominent feature of Tesla’s rivals in the self-driving field. Responding to the inquiry, Musk was firm in his stance that LiDAR is not needed for Tesla’s vehicles to achieve fully autonomous driving, even going so far as to state that rivals being dependent on the technology might be making a grave mistake.
“In my view, it is a crutch that will drive companies to a local maximum that they will find very difficult to get out of. They’re going to have a whole bunch of expensive equipment, most of which makes the car expensive, ugly and unnecessary. And I think they will find themselves at a competitive disadvantage,”
Musk further explained that utilizing sophisticated radar equipment is a far better option for FSD. Tesla is steadfast in using its three-pronged approach featuring redundant forward cameras, forward radar, and near-field ultrasonics will be key to the eventual mastery of autonomous driving.
Musk reaffirmed his stance on using this technology, as it allows vehicles to “see” through snow, rain, dust, and fog — conditions that even experienced drivers find difficult to drive on. Overall, Musk stated that he is optimistic about the development of Tesla’s autonomous driving suite. While Tesla’s CEO admitted that progress has been slow, he asserted that when the company achieves FSD, it would be something truly remarkable.
“It’s also one of those things that’s kind of exponential where it doesn’t seem like much progress, and suddenly, ‘wow.’ It will seem like well this is a lame driver. (Then,) like okay, that’s a pretty good driver. (Then,) like holy cow, this driver’s good,” Musk said.
It’s worth noting that Musk also stated that his beliefs in FSD, LiDAR, and radar technology might be proven wrong in the future. Musk did assert, however, that he is confident in his belief that Tesla’s non-LiDAR approach is the correct way to go.
Now perhaps I am wrong. In which case, I’ll look like a fool. But I am quite certain that I am not,” Musk said.
In a lot of ways, Musk’s statements about LiDAR and the delayed autonomous coast-to-coast drive makes perfect sense. As we noted in a previous report, Tesla’s focus on FSD technology is quite different than its competitors, in the way that the company is attempting to create a system that works under any conditions in any location. The leaders in the field, such as Waymo and GM, on the other hand, are pursuing something different, creating a system that works perfectly in a pre-programmed, set route.
Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it

The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
